You can highlight the mouse cursor path during a recording session, so that it can be used as video tutorial for any software representation.Just like various Screencasting software like Smallvideosoft , Screencast-O-Matic , Webinaria & Windows Media Encoder you can manually set the region of the screen to be recorded like full screen or fixed region if you don't wish to focus on other part of your computer screen rather than main one.
Autopan is the best option available in CamStudio, that I did not found with any other tools.It allows you to record a smaller part of screen, with effective zooming in on particular part what you’re working on, and still you will be able to use the whole screen.
Cursor option allows you to highlight the mouse cursor or your custom cursor even you can hide your cursor with that option,Highlighting cursor will give you a chance to create more effective presentation for your demonstration screencasting video.

As an ideal screencasting software, it allows you to record both the audio and screen video or you can make only video without audio and record your voice later on.You can use either microphone or speaker to record audio for your screencast.
Screen annotations is another best option available in free CamStudio software.It provides you an ability to add screen annotations, baloons in your video.Adding screen annotation is little bit tricky but you can add screen annotation to your video with little or more practice.
